The aim of this public presentation of the HATCH project held in CIRCOLO - Comunita' Degli Italiani Di Pola was to bring the significance of the protection of the Adriatic Sea closer to the youngest and the general public. The event is part of this year’s Croatian Festival of Science 2023 week, which has "Nature and Society" as its theme. Through a rich public presentation program that consisted of a presentation of the HATCH project, an expert lecture, a scientific show and three interactive scientific workshops on the topic of the sea, children and general public were sensitized to the important topics of today: why is the sea important and what we can do to protect it. The public presentation started with the introductory part where the media, the gathered guests and children were welcomed by Daglas Koraca, Ph.D., dean of Istrian University of Applied Sciences and later asst.prof. Vedrana Špada, Ph.D. gave a presentation of the HATCH project, its activities and specific objectives to the gathered audience. This was followed by a lecture on "New entry in the North Adriatic" presented by Neven Iveša, Ph.D. from the Faculty of Natural Sciences of Juraj Dobrila University in Pula. This was followed by the Nutty Scientist team which performed a science show on the theme of the sea. After a short break and regrouping of the children by workstations, interactive workshops and demonstration experiments on the protection of the sea were organized, through which the children and general audience were guided by representatives from the company Tinker LAB, Nutty Scientist and professors and students from the Faculty of Natural Sciences of Juraj Dobrila University in Pula.
